Cherokee County sheriff's spokeswoman Sgt. Marianne Kelley tells news reporters Zoe Reardon is charged with vehicular homicide and other counts in the Sept. 9 crash that killed 3-month-old Riley Hunt, 28-year-old Kaitlyn Hunt and 61-year-old Kathy Deming.
Reardon was 17 when authorities say her SUV hit the trio trying to cross a Woodstock road. The baby died that night. The adults were hospitalized and later died.
Hunt was a Marietta native stationed with the Coast Guard in Port St. Lucie, Florida. Deming was a family friend.
It's unclear whether Reardon has a lawyer. She has been released on bail from the Cherokee County jail.
